Brake bleed question

[DannyKhaKha]

I'm about to do a suspension lift and I got rear long travel (rear only) and they supplied me with braided extended brake lines. I know I have to bleed the brakes and refill the brake fluid, but do I have to bleed the front also? Or can I just replace the rear lines and bleed only the rear brakes and leave the front alone and be fine?

I would flush out to new fluid, that way you know for sure you have good brake pedal feel and new fresh fluid. I would buy some front lines so you do everything at the same time.

You won't have to bleed the fronts, only the rears...BUT as mentioned it would be a good time to flush all the fluid and if you decide to do so replace the old OEM front line with new, the old lines can deteriorate/swell on the inside and restrict fluid flow and if they do if can affect your braking power and also cause the front brakes to "drag".
